Poly(difluoromethylene), α-fluoro-ω-[2-[(1-oxo-2-propenyl)oxy]ethyl]-, homopolymer

Made and used in fluoropolymer manufacturing, specialty coatings, sealants, and engineered plastics [2].

Mostly at work during manufacturing or hot processing (inhaling fumes or dust, skin contact). People near industrial sites may be exposed to PFAS in air or drinking water from releases [1][2].

PFAS can build up in people and some have been linked to changes in cholesterol, immune effects, and developmental impacts. Heating fluoropolymers can generate decomposition fumes that irritate the lungs [1][3].

Workers who make or process fluoropolymers; people living near PFAS production or use sites; pregnant people, infants, and those with asthma or lung disease [1][2].

At work, use local exhaust ventilation, temperature controls, and protective equipment. At home, avoid overheating fluoropolymer‑coated items; check local PFAS water advisories and consider certified filters that reduce PFAS; clean dust with wet methods [1][2].
